You have done a good job so far to make your course accessible. Give yourself a pat on the back!
The last thing you need to do is to add Closed Captions on the slides with navigation. Closed Captions make your eLearning content more accessible and more interesting for the learners. There are many situations where Closed Captions are useful:
- They make your Captivate projects accessible for hearing-impaired students
- They make the project easier to understand for foreign students
- They are useful for learners who have to take the online course in an office and don't want to bother their colleagues with the voiceover narrations
For these reasons (plus ones not listed here), it is a good idea to use Closed Captions each time you add voiceover narration to a slide.
In Captivate, Closed Captions are always associated with a Slide Audio or a Slide Video. They are not supported for object audio, system audio, triggered audio, and event videos...
